The aim of study is to investigate; the effect of increasing several doses P application on soil C, N and P concentration in Long term experiment conditions. Tested hypothesis; increasing P doses application increases soil C, N and P concentration, consequently plant yield can increase. The experiment has establish at University of Çukurova, Faculty of Agriculture, Research and Application field on Arık soil series from since 1998 until update. Four doses of P applied; such as 0 kg P2O5 ha-1 (P0), 50 kg P2O5 ha-1 (P50), 100 kg P2O5 ha-1 (P100) and 200 kg P2O5 ha-1 (P200) with tree replications. Under rain fed condition Adana-99 species wheat (‎Triticum aestivum L.) seeds were sown in November 2017 and harvested at May 2018. Soil samples were taken at different depth (0-15 cm and 15-30 cm) of rhizosphere and non-rhizosphere part at harvest. Soil P concentrations, organic C (OC), inorganic C (IC), soil total carbon C and N were analyzed. Result shown that there is a statistically difference as P concentration, especially in both depth of rhizosphere and non-rhizosphere soils, the best application is P200 compared to the control. As the P dose increased, also soil P content increased linearly. In terms of soil OC content, there was a statistically significant difference at a depth of 15-30 cm in rhizosphere and non-rhizosphere soils and, the best practice was got at P200 application compared to control treatment. In addition, due to increasing doses of P application, the mean soil OC, total N and C content increased. The founded results are support our hypothesis.

Environmental pollution is defined as the disruption of normal ecological balance with emmision of various substances and energy residues as a result of human activities. Animal production is one of the major human activity that enables this emission to increase significantly. Although ruminants play an important role in the effects of animal production on environmental pollutant emissions, the effects of poultry production and broiler production are also worth considering. As in all livestock types, the main factor that has a direct impact on environmental pollutant emissions is feeding for this animal types too. High nutrient needs of broilers and production processes of feed containing these nutrients; greenhouse gas causes increased nitrogen and phosphorus emissions; consequently, they cause air, soil and water pollution to multiply. Changes in protein and amino acid levels or the use of certain feed additives in feeds affect the emission value of broiler production. In addition, the feeding methods also has an effect on these emission values. When these effects are taken into consideration, it is possible to reduce the emission values in broiler production. In this review, environmental effects of broiler nutrition examined in terms of feed production, nutrient emission by manure, presentation of feed and feed form.

Araştırma, farklı azot ve fosfor dozlarının aspirde verim ve verim öğelerine etkisinin belirlenmesi amacıyla Kırşehir ekolojik koşullarında 2016 yılında gerçekleştirilmiştir. Denemede ana parsellere azot (0, 4, 8, 12 kg N/da) dozları, alt parsellere fosfor (0, 4, 8, 12 kg P2O5/da) dozları uygulanmış ve tesadüf blokları bölünmüş parseller deneme desenine göre 3 tekerrürlü olarak yürütülmüştür. Çalışma sonucuna göre azot ve fosfor dozlarındaki değişimin rozette kalma süresine, çiçeklenme süresine, olgunlaşma gün sayısına, bitki boyuna, yan dal sayısına, tabla sayısına, bin dane ağırlığına ve tohum verimine olumlu etki yaptığı belirlenmiştir. Araştırma sonucunda azot ve fosfor dozlarına göre bitki boyunun 48,5 -54,5 cm, yan dal sayısının 2,6-3,6 adet/bitki, tabla sayısının 3,6-4,7 adet/bitki, tabla çapının 19,73-22,28 mm, 1000 tane ağırlığının 34,79-37,43 g, iç-kabuk oranının %57,06-59,37 oranında, tohum veriminin 82,17-182,23 kg/da, ham protein oranı %17,27-19,06 arasında, yağ oranlarının %35,35-38,59 ve yağ veriminin 38,04-60,33 kg/da arasında değiştiği belirlenmiştir. En yüksek verim 12 kg N/da+12 kg P2O5/da gübre dozundan 182,23 kg/da olarak elde edilmiştir.
